2 Claims.

This invention relates in general to a folding display of cardboard and the like, and is more particularly described in connection with a picture frame, although it may have a more general application wherever used- In forming folding displays from a cardboard or other thinsheetmaterial, it is customary to attach a thin printed or lithographed sheet to one sideof'a sheet of cardboard by means of a suitable adhesive, and to prevent warping or buckling. Another sheet, usually without printing and of the-same weight as the printed sheet, is adhesively applied to the other face of the cardboard. is desirable to have all of the printing at one side because it is very diificult to accurately register portions of two printed sheets adhesively secured on oppositesides of the same cardboard.

Informing a folding frame structureof' a single sheet of material in which all of the printing to provide both the picture and a simulation of the frame are on the printed sheet at one side of the cardboard it is required that the sheet or blank be. cut and folded. in a particular manner in order" to provide the desired result.

The present invention is therefore directed to a particular manner of cutting and fol'ding'sheet material in order to simulate a printed frame with a picture therein, all. of the printing therefor being located" on thesame surface of the blank.

A further object of. the invention is in the pro.- vision of an improved corner structure for a frame of this kind.

A still further object of the inventionis in the provision of an improved means locking. the folded sides and edges of a frame near and away from the cornersto hold the corners in close fitting connection.

' A still further. object of the inventionis in the trating, the: method of. folding. and: attaching:- the frameportion to; the picture plane- Fig. 3ris a perspective of one cornerrof. a frame as showndnzli'ig. LWith." onlyone rside. attached Fig. 4: illustrates a corner portion of a" blank fromwhich the frame display is made;

Inorder to resemble a picture with a separatelyappliedframe, it is necessary that the picture' appear to beinserted under or within the inner edge of the frame. This result is obtained in the present invention and from a single sheet of paper or other material printed on one side thereof by folding the edges over inwardly upon themselves about the margin and then folding the edges upwardly and outwardly, then downwardly and rearwardly behind the actual picture plane to simulate a frame overlapping the-picture plane. This requires the corners to'be ciitand the edges to-be cut and scored in a manner and at definite distances so that when the portions are folded, secured together, and overlapped at the corners, aneat, tight-fitting structure' isproduced which may be permanently secured at theyback" of the frame or provided with other locking means along the edges and near the cornerswhioh' will permit the frame portions to be unfolded and packed in. substantially flat condition.

Referringnow more particularly to the drawings, a blank or sheet of cardboardv 20 or other suitable material is printed or" provided with a printed sheet atone side having. a central. printed picture plane 2| Withan unprinted marginliat all sides thereof;-

E'ac'h corner is cut out inwardly to the edge 23 of one ofthe marginal-unprinted portions 22 to provide a foldable frame portion at each side, or edge: of the picture plane. Each foldable frame portion comprises an overlapping strip" 24. connected to the 'picture plane by a partially severing out 2-5 at the rear side thereof; Extending out= ward from the overlapping portion and? connected thereto by folding scores 26 are a. front inclined frame portion 21, an edge frame section 28, and a rear section '29.

In order to make the folded frame fit tightly at the corner, the end of one folding section has an outward straight edge 30 at the end of its overlapping strip 24 continued in the other sections 2'! and 28.substantially in the line of the edge 23, and the edge 3| of the outer or rear section 29 inclining inwardly to a point within the edge 23 if extended. In the other adjacent edge of the corner, one end 32 of the overlapping portion 24 is cut inwardly from the corner of the picture plane 2| to a point substantially the width of the unprinted marginal edge 22, the edge 33 of the frame section 21 is inclined or beveled outwardly at an incline of approximately 45 so that it will fit over andag'ainst the opposite inclined frame section when assembled and the extremity 34 of the edge frame section 28 extends slightly beyond the extremity 35 of the adjacent-rear section 29 so that the end 34 will fit tightly against the opposite edge portion 28 closing any gap thereof at the corner, and at the same time concealing the extremity 35 which does not project beyond the opposite folded frame section at the corner.

In folding each of the frame sections, the overlapping portion 24 is first bent firmly and folds tightly against the marginal edge 22 of the picture plane because of the rear cut 25. This overlapped portion may be fixed in place by an adhesive or by any suitable fastening device such as staples 33 which are permanently or removably placed in position. The inclined frame portion 21 is then folded backwardly at an angle from the attached overlapping portion 24, the marginal frame portion 28 is folded downwardly, and the outer or rear flap portion 29 is folded at the back of the picture plane to V which it is attached by any suitable fastening device or by an adhesive 31 attaching its inner surface to the rear of the picture plane portion. The attachment of the rear portion 29 holds the frame portions 28 and'2'l in the desired angular position and the frame appears to be entirely separate and distinct from the picture plane 2|.

In actually folding these structures at the corners, the two opposite sides having the inclined portions 39 and 3| are usually folded and secured in place and then the opposite'frame portions having the cut extremities 32, 33, and 34 are foldable over to make a tight fitting frame at the corner.

With this folding construction, it is clear that onlyv the picture plane surface 2| and the surfaces of the frame sections 21 and. 28 are required to be printed or lithographed, and they are all on the same side of the blank or sheet, the marginal and overlapping portions 22 and 24 having a definite'relation thereto so that the frame sections may be accurately locked, cut,

I scored, and folded to produce a tight fitting corner structure as well as the appearance of a frame separately applied to a picture.

' Instead of a permanent attachment of the outer flap to the rear side of the picture plane,

various frame attaching means may be employed opening formed by the slots 94 and the cut 95.

be inserted through a slot 63 in an extension 64 of the overlapping portion 24a, the reduced or neck portion of the tongue being seated after insertion through the slot 63 in a reduced portion 65 which engages the neck of the tongue formed by the recesses 62. The resilience of the material is such that the tongues may be inserted through the wider portion of the slot and then is more seated in the reduced portion, holding the frame in its extended position.

In the form shown by Figs. '7 and 8, the picture plane portion 20b is formed with an extending tongue H having flexible end ears 12 formed by scores 13. The outer rim portion 28b is provided with a slot having curved ends or a curved slot 14 with upwardly extending ends 15. The tongue H and the flexible ears are bendable for insertion through the slot, and as soon as they pass through the slot, the ears tend to straighten and assume positions out of register with the curved slot, thereby locking the tongue therein. The tongue and ears must be flexed into registration with the curved slot before they can be withdrawn through the slot. 1 V

In the form shown by Figs. 9 and 10, the picture plane portion 290 in the marginal edge thereof which is covered by the overlapping portion 24 is provided with a tongue (or tongues) 8| with an offsetting score 82 at its hinged edge so that the tongue will overlap a thickness of 'material without breaking. .In the back or rear section 290 is a slot 83 through which each tongue 8| is inserted, the tongue engaging and holding in the recess because of the offset 82 and bending inwardly to overlap the rear faces of the rear flap 290 to which it may be secured by an adhesive, if desired. In this form of the invention, as in the other forms, one of the edge frame portions 280 may be provided with a tongue 85 which is folded under the corresponding opposite edge portion 230 to form a close and tight fitting corner structure.

In the locking construction shown in Figs. 11 and 12, each rear fiap 29d is formed along the edge with inwardly extending tongues 9| having scores 92 at their hinged edges adapting them and a connecting cut forming a tongue 96 under which the inwardly extending tongues 9|v are adapted to be inserted. In the overlapping portion 24d, an opening 91 is provided of substantially the same rectangular dimensions as the These tongues 9| are then offset into the opening 91 and back of the tongue 96 being deflected thereby so that their inner edges engage the edge formed by the out line 95 and also the corresponding edge of the opening 91 thus securely locking the interengaging tongue members in place. In order to disengage the tongues 9|, it is necessary to insert a finger through the. opening 93 and to press thetongues 9| outwardly clear of the cut edge 95 deflecting the tongue, 962.c-

cordingly in so doing. The interlocked edges may.

then be pulled apart and the frame portions disengaged. To set up the frame structure, it is V necessary only to press the tongues "9| inwardly tend toward each other and are hinged on end scores so they may be deflected inwardly into the opening 91 in the overlapping edge portion 24 by the engagement of the tongue 96 at the back of the display.

In all of the forms shown, the shape of the frame may be varied somewhat depending upon the type of fastening device used, from a straight rectangular form as shown in Fig. 1 or with the marginal edges inclined more or less inwardly as shown in Figs. 5 to 12. In the forms shown by Figs. 5 and 6, and 7 and 8, it is desirable to incline the frame edge portions inwardly to cover the projection of the locking tongues, but in the forms shown in Figs. 9 to 12, the locking members are located at the back and the marginal edges may be inclined inwardly as shown, or outwardly, if desired.

In all forms of the invention as shown, the complete structure may be made of one sheet of material, cut, scored, and folded as set forth with the sheet printed on one face only to provide a picture and a separate appearing frame when folded. This same construction may be utilized in a variety of ways for display devices without limiting it to the representation of a framed picture.

I claim:

1. In a folding display, a single sheet, cut, scored, and folded to provide a picture portion in an apparently separate frame, the sheet being angularly cut away at the corners, the sides having parallel scores to form connected, overlapping front frame, marginal frame, and'back sections, the front frame sections fitting together at the corners to form a beveled raised corner structure, and defiectible tongue and slot means engaging the rear section between the ends of the frame section at the back of the display and i of the display,

within the marginal edge covered by the frame so that the frame fastening means is hidden from the front of the display, said means comprising a scored rearwardly extending tongue and the rear frame section formed with a slot through which the tongue is inserted, the scored portion engaging the tongue in the slot, and the tongue extending inwardly from the edge of the-frame in substantially closed position.

2. In a folding display, a single sheet, cut, scored, and folded to provide a picture portion in an apparently separate frame, the sheet being angularly cut away at the corners, the sides having parallel scores to form connected, overlapping front frame, marginal frame, and back sections, the front frame sections fitting together at the corners to form a beveled raised corner structure, and defiectible tongue and slot means engaging the rear section between the ends of the frame section at the back of the display and within the marginal edge covered by the frame so that the frame fastening means is hidden from the front said means comprising a resilient tongue formed from and located in a recess in the picture plane section at the marginal edge thereof and covered by the frame at a distance from each corner of the display, the tongue extending outwardly and an edge of the recess extending adjacent the outer edge of the tongue, the rear frame section having a pair of tongues extending toward each other and inwardly from the edge of the rear section with offset hinged portions so that the pair of tongueswhen inserted below the first tongue in the recess will be deflected thereby to engage the said edge of the recess for releasably interengaging and locking the rear frame portions to the picture plane portion of the display.
